ATTORN EY Patented.

VARIABLE This invention relates to "variable corr densers and to that type adapted for ria-:lio

use.

One of the. object; oi the invention ie to provide a variable eoudenner constructed in such :i novel manner that it con lio controlled with extreme accuracy so ilnitvorc-.zit seleetivity in tuning is possiblerantl with very litt-le effort on the part. of the operator.

IAnother object of the invention is,A to provide a variable oondenserthat is very simple in f-onstruction. inexpenriire to rininuriftiutny and Contains few parte for the maxiiuon'i re suits obtained.

This invention also tonsiste in Certain other features of construction and in they combination and arrangement of the several parte` to he hereinafter fully demihed iilus'- trated in the accompanying drawings and speoiiieeily pointed out in the appended claims.

In describing my invention in detail. ret @rence will be had to the :ieeonipanying drawings wherein iilie eherateteie denote like or correspondingv parts tlirougliout the sew eral views, and in which:

Figure lis n rear elevation of the conn denser forming the. subject matter of the present invention and show-ing the plates thereof in open position.

Figure 2 is a fragmentary rear elevation and showing the plates in closed position.

Figure 3 is an edge. elevation showing the condenser mounted.

Referring to the drawings in detail the reference numeral l indicates the body of the, condenser which forms the subject met ter of the present invention and passing through the body above the central portion thereof is e Shaft 2 mounted in e suitable hearing secured in said body es will! be apparent upon. inspection oiFigure 3 of the drawings.

Secured to the inner end of said shaft 2 is E disk 3 provided with epair of spaced spraly'arranged slots 4 which arev :idepted to receive for slidable. movement therein pins extending inwardly from plates and 'Il The@ pins K ere arranged at the juncture ,cif the Shank S of the pla-tes and the shanke @lave their ovrer ends mounted for pivotal ,movement upon screws 9 which are secured n the body end surrounding heee serewe ele sleeves() whereby the plates,

portions, of the plates are sul)- "fny reelfingiilur Shape in formation as in Fig i :in/l the pluies are so .en that the body portions cooperee-oli other :ind are arranged to reed pairs for that purpose.

to the outer end of the shaft 2 oi the usual construct-ion, but it. szlioultl he noted here, that this dial is provided with eruduetione disposed about its entire rirrumi'erenee fanti arranged on the. outer faire ther-ent and is provided with a knob '1Q wherehy the dial is roteteth 'or im! porting rotation to the Shaft and slotted eek respectively Secured to the body 1 is one end oi" lettic Springs which engage the outer surface of the, plates 6 and 7 as Shown in Figure i so as to retain the pins 5 upon tir'A outer face oi' the Slots 4 for a purpose which will he 'presently apparent.

Fronti the above description and disclosure in the drawings, it will oe obvious that have provide :i variahie condenser including inni .lile inenting: plates having connection with stromentalit);l of pins; 5 and oy employing the spring l?? tor retaining the pins 5 upon the inner ieee oiI the slots 4, it will be 0bvions that all lostniotion between the disk und platee vvili he tril'en iip'and thereby provide :curate tuning. Again, by employing the novel Construction as above set forth togetlier with the dial having graduations about its entire circumference, the condenser can be controlled with extreme accuracy with very little effort. on the. purtof the operator so that greet seleetivity in sible.

lt is thought from the 'foregoingdescription that the advantage-s and novei features l ,i .ion will he readily apparent..

l desire to be understood that I may ineke changes in the construction and in the combination and arrangement of the several parte, provided that. Such changes fall within the of the appended claims.

What Claim is:

L A varieiile condenser of the character described Comprising a body, plates pivotally ensured to said body. a shaft .mounted for rotation through said body, a disk secured to one end of said shaft and being prot ded with siete arranged inspire"A formation thereinpins extending from platee and moiinted in seid slots, and'sprmgs Sil bearing against/said plates for retaining the pins againstl the inner face of said slots.

2. A variable condenser of the character described comprising a body, plates having 5 Shanks pivotally secured to said body in spaced relation thereon, a shaft mounted for rotation through said body, a. disk having slots spirally arranged therein, pins extending inwardly from said plates and received in said slots, leaf springs secured in said body and bearing against said plates for retaining the pins against the inner face of said slotsa @ud a dial also secured to said shaft and' provided with graduations extending about its entire circumference.

In testimony whereof I aix my signature.
